Referring now to the figures, l5 represents a frame comprising a base 16 and upright portions l1. Resting upon the base is an electric motor l8 having a base l9. This base is secured to a transverse plate 2| upon the base by fastening screws 22. An electric cable 23 extends from the motor to an electric switch 24 mounted upon the side or upright portions [1. From this switch extends an electric supply cable 25 having a plug 26 thereon adapted to fit any wall receptacle. This cable extends through a grommet 2! in the portions ll. The switch hasan operating lever 28 accessible from the exterior of the machine and can be turned on to start the electric motor I8 and off to stop the operation of the same. The electric motor has a pinion 29 which meshes with a gear 3| on a shaft 32 journalled between the upright portions in bearings 33 and 34,'Fig. 3. The shaft 32 has a gear 35 which meshes with a large gear 36 on shaft 31 journalled in the upright portions ll by means of bearing brackets 38 and 39. The shaft 31 extends exteriorly of the upright portions I1 and has a pinion 4| thereon.

Lying above the shaft 31 and journalled in brackets 42 and 43 in the upright portions, Fig. 4, is a roller shaft 44 having a roller 45 fixed therewith. The sprocket pinnion 4| has a sprocket chain 45 connected to it and which extends to a large sprocket 4'1 fixed on the-shaft M, Figs. 1 and 4, to drive this shaft 44,'the"r'ol1er 45 and conveyor belt 48' extending over the roller.

Also on the shaft is a small sprocket 59, Fig. 4, which is connected by a sprocket chain 5! with a sprocket 52 on a shaft 53 of a belt roller 54 carrying the belt 48. This shaft 53 has a gear 55 with a dwell portion 56 thereon and with teeth 51. The teeth 51, when they come into relationship with a gear 58, Fig. 2, on a shaft 59 and serving as an idler gear, will drive the gear 58 to in turn drive a large gear BI on which a flat sided rotatable element 62 is fixed and against the sides of which cookies are formed in a manner to be hereinafter described. The beltconveyor 48- is supported upon a sheet deck63."

Above the belt 48 is a top belt 64 carried upon rollers 65 and 66 journalled upon a frame 68 having a bottom plate 69 against which the belt 64 can be pressed and wherein upon'adjustment of the frame 68, the belt 64 can be brought closer to the belt 48 or elevated to a greater'extent therefrom. The adjustment is'effectediby a-wheel= II having a shaft I2 extending through a top piece 13 forming a partof the upright portions of the frame. In order'that indications can be given as to the thickness ofithe-cookieamaterial to be passed by the belts48iand 64*; a rack-element' ISI is-made secure to the adjustable frame 6| and this 1'801('-. element meshes with a. pinion 16' h'aving 'a'nindicatingarm 'IIfflxed to the same and adapted to be adjusted" over" an: indicating plate 18 fixed by screws 19 to-tlie =top part 113'. on the uprightportions- II' of theframe; Fig. 10.. A guide slot 8 Us provided iii-the frame-portions- I I to receive extension 82 of the conveyorrroller 54 to retain'the'fi'ame-BB -and the conveyor roller-54 against longitudinal displacement.

A tension spring: 93- acts upon an arm-fikcarrying the roller 92';

Abovethe r'ear'end of the belt-'48 are two-rollers-95- and96. Above these rollers is a removable hopper- 91 intowhich the; cookie dough can: be extended tobefed' to the rollers- 95 and- 96 and from the rollers to the" conveyor belt" 48' to be flattened to thesizedesired dependingupon the adjustment'of the adjusting-wheel II and of the upper belt arrangement 64; Shaft 44* has a sprocket- 98:which is connectedby a chain 9'9'to aspi'ock'et IUI- on-the-roller 96 The rollers 95? and 36 include transverse bars IDZrespectivelywhich cling to the-dough to'pull'the samefrom the hopper 91. The roller 95 -is driven from the belt-roller:65 througli-a chain I 03; Thehopper 31 has brackets I04 extending fromthe same adapted to respectively receive locking bolts I65 which arefi'xed-to the brackets by wing nuts I661 The-dough; upon passing'between the-belts, is flattened tothe proper thickness and-is deposited" upon one ofthe'flat' sides of the fiat sided rctatable support 62;

Above the fiat sided rotary support 62- is a transversely extending plate I06, Fig; 5; which carries upstanding bracket I I39 with longitudinal- 1y extending pins I III extending therefrom and about which are springs I I I; These-springs react against an abutment or bracket I-I2 fixed toa sliding plate II3 whichhas a pluralityoi'longitudihally spaced elongated slots I'I'4 andan upstanding roller I I5 thereon; This roller is engaged-by a rotary cam I I6 fixed to a shaft II"! journall'ed in a bearing bracket II 8 mounted'upon thefr'ame IO'. This cam I IBwill cause thesliding plate I l3 to be moved laterally-against the action of the springs I I I and the springs upon the roller II5 being dropped from high point IIB on the cam will return the plate II 3 to the right as viewed in Fig. 5. The shaft II! has a sprocket I I9 that is operated by a sprocket I2I connected with a sprocket chain I22 on the shaft 53 of the roller 54 of the lower belt 46.

The sliding plate II3 carries'a'depending cam plate I24- engagin withrollers I25 respectively of cookie forming mold assemblies I26.

These assemblies I26 have an inverted cutting cup I2'I with a cutting edge I28 and an inner forming. partv I29having radially extending ribs for formingcdepressions I3I in the cookie, Fig. 6. The'part' I29 has a stem I33 extending upwardly. Above the member I29 on the stem I33 is a bracket I34 having a plate I35 secured to it by screws I36. In the plate I35 are holes I31 through which pass respectively pushing elements or rods. I38 for. removing. the cutand formed cookie from the mold assembly. This element I38:has an enlargement.

An adjustable fluid container I 5 I=' is mounted on the frame I5. and distributes through. a: tube; I52 a fluid-for deposit onxaplatei- I53 tojbe dripped upon the cookie dough. Thisrfluidmay: prevent the cutting cup from sticking to the-doughzafter the-cookie has beencut.

The rotatable support 62.has afiat sided portion I55 on which a braking arrangement-i I56 acts to retain the supports as eachflat'side of the support is. stepped toits position to receive; the cutting and forming assemblies The rotatable support'carries a sprocket I 5'I'-which oon-- nects by a'chain I58 with a-small sprocket I59=of adischarging conveyor device I6'I disposedbeneath the supports and adapted to receive the cut cookies I32 to discharge them'upon acookie sheet or into a container or thelike.

The rotary support is journaled in bearingbrackets I63, Fig. 5, and extending laterally therefrom is a counting'device I64 having a gear I65- meshihg with a gear I66. Through a window I81 of the counting device the number of cookies which have been cut'can be read; This counting device can be viewed moreclearly in Fig. 11- and includes internal reels I63 and I69 over which a tape IlI bearing numbersis-extended;

It should nowbeappa-rent that therehas been provided an automatic cookie cutting and forming machine wherein a rotatable fiat sided support isoperated in step by step fashion to bring the fiat sides beneath the cutting and'forming devices and to receive the dough preparatory to the operation of the cutting and forming devices which, at the proper timing interval, are brought ontothecookie dough to sever the cookies I32 therefrom. Automatically the cookie cutting devices are elevated and their pushing elements will extract the cookies from the inverted cup shaped members and drop them onto the fiat portion 56 and the teeth portion 51, Fig. 2.
